Abstract: A polyamide/poly(arylene ether) composition includes specific amounts of a block copolymer, glass fibers, and a compatibilized blend of at least two polyamides and a poly(arylene ether). The composition is particularly useful for molding automotive under-the-hood components that exhibit an improved balance of moldability, heat resistance, and resistance to brittle failure.

Abstract: A composition containing particular amounts of a poly(arylene ether), a poly(arylene sulfide), an electrically conductive carbon black, and glass fibers is particularly useful for molding heat-resistant articles suitable for electrostatic painting. Compared to a corresponding composition without the poly(arylene ether), the composition exhibits improved paint attraction and markedly improved paint adhesion, and it allows the use of a lower level of conductive carbon black to achieve the same electrical conductivity. The composition thus provides an excellent balance of impact strength, electrical conductivity, and paint attraction and adhesion.

Abstract: A sampling system for performing a spectroscopic analysis on a polymer during its production is described. The system includes a transfer tube capable of transporting the polymer from a production site to a storage site. The tube includes an entry site connected to the production site; and an exit site connected to the storage site. A transparent window is inserted into the wall of the tube, and a door or other barrier is provided to stop the flow of polymer through the tube, so that it accumulates against the window. A spectroscopic device situated outside the tube then takes a reading of the polymer through the window, to perform the desired analysis. Related methods are also described.
